Teen pop/R&B duo MKTO are popping up everywhere these days: For one thing, we’ve been spinning the boys’ second single, Classic, since last June, and Malcolm Kelley and Tony Oller are set to drop their self-titled debut album on Jan. 31.

Malcolm (who, fun fact, used to play Walt on LOST) and Tony recently stopped by SiriusXM Hits 1 to perform Classic. Check out their performance below, and try to resist the urge to scream “WAAAAAAALT!!!” while you watch.
